AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N
Remote low-complexity access with an existing low-privileged account and no interaction; a bypass crossing the security boundary (S:C) yields read-only disclosure, so C:H and I:N/A:N.

Lifecycle Timeline
2DescriptionCVE.org
ColdFusion is affected by an Improper Input Validation vulnerability that could result in a Security feature bypass. A low-privileged attacker could leverage this vulnerability to bypass security measures and gain unauthorized read access. Exploitation of this issue does not require user interaction. Scope is changed.
AnalysisAI
Security feature bypass in Adobe ColdFusion allows a low-privileged, network-based attacker to defeat access controls and obtain unauthorized read access to data outside their intended authorization boundary. Adobe PSIRT classifies the root cause as improper input validation and tags it an authentication bypass; the CVSS 3.1 score is 7.7 with a changed scope, reflecting impact that crosses a security boundary. No public exploit has been identified at time of analysis, and no EPSS or CISA KEV data was provided.
Technical ContextAI
ColdFusion is Adobe's commercial rapid web-application development platform and application server (CFML runtime, administrator console, and associated services), commonly deployed to serve dynamic web applications and APIs. The flaw is classified as CWE-20 (Improper Input Validation), meaning the software fails to correctly validate attacker-supplied input before using it in a security-relevant decision, and here that failure manifests as a security-feature/authentication bypass. Because the CVSS scope is Changed (S:C), the vulnerable component's flaw grants access to resources managed by a different security authority, consistent with a bypass that reaches data beyond the attacker's own privilege context.
RemediationAI
Apply the updates described in Adobe Security Bulletin APSB26-82 (https://helpx.adobe.com/security/products/coldfusion/apsb26-82.html); a patch is available per the vendor advisory, though an exact fixed version number was not included in the provided data and should be taken from that bulletin. As compensating controls until patching completes, restrict network access to the ColdFusion Administrator and application endpoints to trusted management networks, tighten the privileges granted to low-trust authenticated accounts (since exploitation requires PR:L), and monitor logs for anomalous read/access patterns against protected resources; note that restricting Administrator access may disrupt legitimate remote administration and should be coordinated with operations.
